[Gdal-dev] Creating overviews in different folder

I would like to be able to create external overviews in a different folder from the original file. The data might be on a shared nework drive where i don't have write access and it could be very handy to be able to be able to keep the data from others clean from my files.

It would be very easy to use if you could supply the overview filename to BuildOverviews and GDALOpen but that would break the binary compatibility. 

GDALDefaultOverviews allready supports overviews with a different location trough the pszBasename parameter of Initialize and BuildOverviews.

Any thoughts on how to change/add the interface to support this?
